Researchers say delivering the flu vaccine under the tongue may not just scrap the need for needles, it could also provide more effective protection.
Experiments on mice showed that delivering the vaccine "sublingually" protected the rodents against flu without any obvious side-effects.

It is thought this method may prove more effective than jabs as it protects the area where the virus first enters.

The study appears in the Proceedings of the National Academy of Sciences.
